i have one attribute called most popular with defatul Yes/no configuration by magento i followed
1) To add using Magento Backend you need to follow below steps
a) Goto Catalog->Attributes->Manage Attributes
b) Select the attribute you want to add in Sort By option. Suppose you need to add a Sort By popular Option.
c) Goto Brand Attribute and check for "Used for Sorting in Product Listing".
d) Make it YES
but still i didn't get it work.
i have trace magento's collection with this sort but its not adding any order in collection as below for popular sort,
SELECT `e`.*, `search_result`.`relevance`, `price_index`.`price`, `price_index`.`tax_class_id`, `price_index`.`final_price`, IF(price_index.tier_price IS NOT NULL, LEAST(price_index.min_price, price_index.tier_price), price_index.min_price) AS `minimal_price`, `price_index`.`min_price`, `price_index`.`max_price`, `price_index`.`tier_price`, `cat_index`.`position` AS `cat_index_position` FROM `catalog_product_entity` AS `e` INNER JOIN `catalogsearch_result` AS `search_result` ON search_result.product_id=e.entity_id AND search_result.query_id='2' INNER JOIN `catalog_product_index_price` AS `price_index` ON price_index.entity_id = e.entity_id AND price_index.website_id = '1' AND price_index.customer_group_id = 0 INNER JOIN `catalog_category_product_index` AS `cat_index` ON cat_index.product_id=e.entity_id AND cat_index.store_id='1' AND cat_index.visibility IN(3, 4) AND cat_index.category_id = '2' LIMIT 12
Price sorting is correct as below
SELECT `e`.*, `search_result`.`relevance`, `price_index`.`price`, `price_index`.`tax_class_id`, `price_index`.`final_price`, IF(price_index.tier_price IS NOT NULL, LEAST(price_index.min_price, price_index.tier_price), price_index.min_price) AS `minimal_price`, `price_index`.`min_price`, `price_index`.`max_price`, `price_index`.`tier_price`, `cat_index`.`position` AS `cat_index_position` FROM `catalog_product_entity` AS `e` INNER JOIN `catalogsearch_result` AS `search_result` ON search_result.product_id=e.entity_id AND search_result.query_id='2' INNER JOIN `catalog_product_index_price` AS `price_index` ON price_index.entity_id = e.entity_id AND price_index.website_id = '1' AND price_index.customer_group_id = 0 INNER JOIN `catalog_category_product_index` AS `cat_index` ON cat_index.product_id=e.entity_id AND cat_index.store_id='1' AND cat_index.visibility IN(3, 4) AND cat_index.category_id = '2' ORDER BY `price_index`.`min_price` asc LIMIT 12
is there any solution to make this work ?
your help will be very appreciated.
